150 To 30000Khz Oscillator
A capacitor in series with the crystal can be utilized to adjust the output frequency of the oscillator. The value can range between 20 pF and 0.01 µF, or it can be a trimmer capacitor. The values are approximate and...
Basic RF Oscillator circuit diagram
Experimenting with the size of the coil and the number of turns can influence the frequency and signal output of the oscillator. The signal can be received using a standard FM radio receiver. The input signal should be coupled via...
simple electronic organ
This electronic organ is simple to construct and can provide hours of enjoyment, particularly for children. The circuit is fundamentally an emitter-coupled oscillator consisting of transistors T2 and T3. A square wave voltage can be sampled from the collector of...
Audio Test Oscillator
As a piece of test equipment, an audio oscillator has to be considered essential for anyone working in with hi-fi gear. Together with an audio millivoltmeter (as described in Project 16), and even better if you have access to an...
Electronic Drum Synthesizer
The circuit consists of two twin-T oscillators set below the oscillation threshold. To initiate oscillation, a touch on the Touch Pad is required. The schematic diagram illustrates the circuit, where different touch patterns on the pads can create a variety...
automatic dual output display circuit diagram
This circuit lights up ten bulbs sequentially, first in one direction and then in the opposite direction, creating an appealing visual effect. In this circuit, gates N1 and N2 form an oscillator. The output of this oscillator serves as a...
Metal detector 4
The metal detector circuit comprises a detection oscillator, a reference oscillator, a mixer, and a signal display, as illustrated in Figure 8-70. The detection oscillator circuit is made up of the time base oscillator IC1, inductor L1, potentiometer RP1, diode...
The door bell circuit
Figure 1 illustrates an economical and straightforward Gate Alarm designed to operate using a small universal AC-DC power supply. IC1a functions as a fast oscillator, while IC1b serves as a slow oscillator. These two oscillators are integrated through IC1c to...
Electronic Music Maker
This electronic music maker utilizes an astable oscillator circuit that is regulated by a photocell. The intensity of light falling on the photocell influences the tone. By enclosing the circuit within a box, it is possible to manipulate the light-sensing...
